Introduction

2.1

Overview

The Giga-tronics GT-1050B Microwave Power Amplifiers are high-performance solid-state microwave power

amplifiers. The Giga-tronics GT-1050B provide excellent pulse fidelity, low intermodulation distortion, high

linearity and superior gain flatness without the warm-up time, drift or aging issues of traveling wave tube

amplifiers (TWTA). They feature low noise figure, low harmonics and spurious content, and are highly tolerant

to load mismatch.

GT-1050B:

•

Frequency Range: 2 GHz to 50 GHz.

•

2.4 mm compatible 1.85 mm (f) V input connector.

•

2.4 mm compatible 1.85 mm (f) V output connector.

2.1.1

Features and Benefits of the GT-1050B Microwave Power Amplifier

•

25 dB nominal gain over the 2 GHz to 50 GHz frequency range.

•

Ideal for testing in R&D labs, ATE systems, wireless communications applications and defense EW

systems.

•

Small size allows easily placing the amplifier close to the device under test.
